The Timney AR Calvin Elite Trigger (brand part no. 660CE) is a complete, drop-in single-stage trigger assembly built for AR and M4-pattern rifles, factory-tuned to a crisp, zero-creep pull with no gunsmithing required. A 5-pound hammer spring keeps ignition reliable while the pull weight itself runs a light 1.5 to 2 pounds, and the trigger shoe adjusts for length of pull, cast, and height so each shooter can dial in their own custom fit and positive finger contact. Timney builds it to drop straight into any mil-spec AR lower, ready to shoot with no further adjustment needed.
